Nthuav cov khoom perlite xa mus rau cov thermal rwb thaiv tsev refractory khoom ua los ntawm perlite raws li lub ntsiab tivthaiv. Maas perlite perlite cov khoom lag luam yog tsim los ntawm kev npaj, kev kuaj xyuas, thiab kom qhuav nrog cov binder, tus neeg tiv thaiv dej, thiab nplaum.
Xws li cov cement, tshuaj phosphote, thiab lwm yam, tom qab sib tov, sib sau, ua kom qhuav, ci. Qhov ceev ntawm expanded perlite yog qhov me me, feem ntau tsuas yog 40-120 kg / m, thiab kev ua kom rov ua haujlwm feem ntau yog {1} degree. Qhov nyiaj ntau tshaj plaws ntawm cov khoom ua los ntawm cov sib txawv sib txawv yog qhov sib txawv, thiab feem ntau yog qis dua 1000 degree.
